Is there an API way to see all running builds across all users?

We used to be able to see all queued or running builds under Running (#/#) in the web UI (Enterprise v2.1.15). We installed a fresh instance at 2.2.16 and now seem to only be able to see our running builds. So I am interested in enabling this, but also looking for a programmatic way to see this. It looks like it would be a painful process of querying every user or repo to see if it has any running builds. I suspect this could also lead to duplication of reporting if multiple people have access to a repo. It seems this information must be available somewhere for Travis to manage, such as a DB we could query.
